PART 3. POWER BOILERS
380:25-5-5. Age limit of existing boilers
(a)
The age limit of any boiler of non-standard construction, installed prior to the date the Act became effective, shall be 30 years except that, after a thorough internal and external inspection, and when required by the Inspector, a hydrostatic pressure test of 1.5 times the allowable working pressure and held for a period of at least 30 minutes, during which no distress or leakage develops, having other than a lap-riveted longitudinal joint may be continued in operation at the working pressure determined by Section 380:25-5-7. The age limit of any non-standard boiler having lap-riveted longitudinal joints and operating at a pressure in excess of 50 psig shall be 20 years. This
32
type of boiler, when removed from an existing setting, shall not be reinstalled for a pressure in excess of 15 psig. A reasonable time for replacement, not to exceed one year, may be granted by the Chief Boiler Inspector.
(b)
The age limit of boilers of standard construction installed prior to the date this law became effective shall be dependent on thorough internal and external inspection and where required by the Inspector, a hydrostatic pressure test not exceeding 1.5 times the allowable working pressure. If the boiler, under these test conditions, exhibits no distress or leakage, it may be continued in operation at the working pressure determined by Section 380:25-5-6.
(c)
The shell or drum of a boiler in which a lap seam crack develops along a longitudinal lap-rivet joint shall be condemned. A lap seam crack is a crack found in lap seams extending parallel to the longitudinal joint and located either between or adjacent to rivet holes.
380:25-5-6. Maximum allowable working pressure for standard boilers
The maximum allowable working pressure for standard boilers shall be determined in accordance with the applicable provisions of the edition of the ASME Code under which they were constructed and stamped or the latest edition of the ASME Code.
380:25-5-7. Maximum allowable working pressure for non-standard boilers
(a) Allowable working pressure. The maximum allowable working pressure of a non-standard boiler shall be determined by the strength of the weakest section of the structure, computed from the thickness of the plate, the tensile strength of the plate, the efficiency of the longitudinal joint or tube ligaments, the inside diameter of the weakest course and the factor of safety allowed by the rules of this Chapter. Non-standard boilers with welded seams shall not be operated at pressures exceeding 15 psig for steam, 30 psig for water.
TStE = maximum allowable working pressure, psi
RFS
Where:
TS = ultimate tensile strength of shell plates, psi
t = minimum thickness of shell plate, in weakest course, in inches
E = efficiency of longitudinal joint:
For tube ligaments, E shall be determined by the rules given in Section I of the ASME Code. For riveted construction, refer to the National Board Inspection Code. For seamless construction, E shall be considered 100%.
R = inside radius of the weakest course of the shell, in inches FS = factor of safety permitted.
(b)

(e) Factors of Safety. The working pressure shall be decreased by the Inspector if the condition and safety of the boiler warrants it using the applicable code as a guideline. The following factors of safety represent minimum values to be used. The lowest factor of safety permissible on existing installations shall be 4.5, except for horizontal-return-tubular boilers having continuous longitudinal lap seams more than 12 feet in length, the factor of safety shall be 8. When this latter type of boiler is removed from its existing setting, it shall not be reinstalled for pressures in excess of 15 psig.
380:25-5-8. Cast iron headers and mud drums
The maximum allowable working pressure on a water tube boiler, the tubes of which are secured to cast iron or malleable iron headers, or which have cast iron mud drums, shall not exceed 160 psig.
380:25-5-9. Pressure on cast iron boilers
The maximum allowable working pressure for any cast iron boiler, except hot water boilers, shall be 15 psig. See Sections 380:25-5-21, 380:25-5-22, and 380:25-5-24.
380:25-5-10. Safety valves
(a)
The use of weighted-lever safety valves or safety valves having either the seat or disk of cast iron are prohibited; valves of this type of construction shall be replaced by direct, spring-loaded, pop-type valves that conform to the requirements of ASME Code Section I.
34
(b)
Each boiler shall have at least one ASME/National Board certified safety valve, and if it has more than 500 square feet of water-heating surface, or an electric power input of more than 1,100 kw, it shall have two or more safety valves of the same type.
(c)
The valve or valves shall be connected to the vapor space of the boiler, independent of any other steam connection, and attached as close as possible to the boiler without unnecessary intervening pipe or fittings. Every safety valve or safety relief valve shall be connected so as to stand in an upright position, with spindle vertical. Where alteration is required to conform to this requirement, owners or users shall be allowed reasonable time in which to complete the work as permitted by the Chief Boiler Inspector.
(d)
No valves of any description shall be placed between the safety valve and the boiler nor on the discharge pipe, if used. When an escape pipe is used, it shall be at least the full size of the safety valve discharge and fitted with an open drain to prevent water lodging in the upper part of the safety valve or safety valve discharge pipe; it shall be located close to the safety valve outlet or the discharge pipe shall be anchored and supported securely. All safety discharges shall be so located or piped as to be carried clear from walkways or platforms.
(e)
The safety valve capacity of each boiler shall be such that the safety valve or valves will discharge all the steam that can be generated by the boiler without allowing the pressure to rise more than 6% above the highest pressure to which any valve is set, and in no case to more than 6% above the maximum allowable working pressure.
(f)
One or more safety valves on every boiler shall be set at or below the maximum allowable working pressure. The remaining valves may be set within a range of 3% above the maximum allowable working pressure, but the range or setting of all the safety valves on a boiler shall not exceed 10% of the highest pressure to which any valve is set.
(g)
When two or more boilers, operating at different pressures and safety valve settings, are interconnected, the lower pressure boilers or interconnected piping shall be equipped with safety valves of sufficient capacity to prevent overpressure, considering the maximum generating capacity of all boilers.
(h)
In those cases where the boiler is supplied with feed water directly from water mains without the use of feeding apparatus (not to include return traps), no safety valve shall be set at a pressure greater than 94% or the lowest pressure obtained in the supply main feeding the boiler.
(I)
If the safety valve or safety relief valve capacity cannot be computed or if it is desirable to prove the computations, it may be checked in any one of the three following ways, and if found insufficient, additional capacity shall be provided:
(1)
By making an accumulation test, which consists of shutting off all other steam discharge outlets from the boiler and forcing the fires to the maximum. The safety valve capacity shall be sufficient to prevent a rise of pressure in excess or 6% of the maximum allowable working pressure. This method should not be used on a boiler with a superheater or reheater;
35
(2)
By measuring the maximum amount of fuel that can be burned and computing the corresponding evaporative capacity(steam generating capacity) upon the basis of the heating value of this fuel. These computations shall be made as outlined in the Appendix of the ASME Code, Section I;
(3)
By measuring the maximum amount of feedwater that can be evaporated. When either of the methods outlined in Section 380:25-5-10(I)-(2) & (3) is employed, the sum of the safety valve capacity shall be equal to or greater than the maximum evaporative capacity (maximum steam generating capacity) of the boiler.
380:25-5-11. Boiler feeding
(a)
Each boiler shall have a feed supply which will permit it to be fed at any time while under pressure.
(b)
A boiler having more than 500 square feet of water heating surface shall have at least two suitable means of feeding, at least one of which shall be a feed pump. A source of feed at a pressure 6% greater than the set pressure of the safety valve with the highest setting may be considered one of the means. Boilers fired by gaseous, liquid, or solid fuel in suspension may be equipped with a single means of feeding water provided means are furnished for the shutoff of heat input prior to the water level reaching the lowest safe level.
(c)
The feedwater shall be introduced into the boiler in such manner that it will not be discharged close to the riveted joints of shell or furnace sheets, or directly against surfaces exposed to products of combustion, or to direct radiation from the fire.
(d)
The feed piping to the boiler shall be provided with a check valve near the boiler and a valve or cock between the check valve and the boiler. When two or more boilers are fed from a common source, there shall also be a valve on the branch to each boiler between the check valve and the source of supply. Whenever a globe valve is used on feed piping, the inlet shall be under the disk of the valve.
(e)
In all cases where returns are fed back to the boiler by gravity, there shall be a check valve and stop valve in each return line, the stop valve to be placed between the boiler and the check valve, and both shall be located as close to the boiler as is practicable. It is recommended that no stop valves be placed in the supply and return pipe connections of a single boiler installation.
380:25-5-12. Water level indicators
(a)
No outlet connections (except for damper regulator, feedwater regulator, low water fuel cutout, drains, steam gauges, or such apparatus that does not permit the escape of an appreciable amount of steam or water therefrom) shall be placed on the piping that connects the water column to the boiler. The water column shall be provided with a valved drain of at least 3/4 inch pipe size, the discharge to be piped to a safe location.
(b)
For all installations where the water gauge glass or glasses are more than 30 feet above the
36
boiler operating floor, it is recommended that remote water level indicating or recording gauges be installed at eye height above the operating floor.
380:25-5-13. Steam gauges

380:25-5-9. Pressure on cast iron boilers
The maximum allowable working pressure for any cast iron boiler, except hot water boilers, shall be 15 psig. See Sections 380:25-5-21, 380:25-5-22, and 380:25-5-24.
380:25-5-10. Safety valves
(a)
The use of weighted-lever safety valves or safety valves having either the seat or disk of cast iron are prohibited; valves of this type of construction shall be replaced by direct, spring-loaded, pop-type valves that conform to the requirements of ASME Code Section I.
34
(b)
Each boiler shall have at least one ASME/National Board certified safety valve, and if it has more than 500 square feet of water-heating surface, or an electric power input of more than 1,100 kw, it shall have two or more safety valves of the same type.
(c)
The valve or valves shall be connected to the vapor space of the boiler, independent of any other steam connection, and attached as close as possible to the boiler without unnecessary intervening pipe or fittings. Every safety valve or safety relief valve shall be connected so as to stand in an upright position, with spindle vertical. Where alteration is required to conform to this requirement, owners or users shall be allowed reasonable time in which to complete the work as permitted by the Chief Boiler Inspector.
(d)
No valves of any description shall be placed between the safety valve and the boiler nor on the discharge pipe, if used. When an escape pipe is used, it shall be at least the full size of the safety valve discharge and fitted with an open drain to prevent water lodging in the upper part of the safety valve or safety valve discharge pipe; it shall be located close to the safety valve outlet or the discharge pipe shall be anchored and supported securely. All safety discharges shall be so located or piped as to be carried clear from walkways or platforms.
(e)
The safety valve capacity of each boiler shall be such that the safety valve or valves will discharge all the steam that can be generated by the boiler without allowing the pressure to rise more than 6% above the highest pressure to which any valve is set, and in no case to more than 6% above the maximum allowable working pressure.
(f)
One or more safety valves on every boiler shall be set at or below the maximum allowable working pressure. The remaining valves may be set within a range of 3% above the maximum allowable working pressure, but the range or setting of all the safety valves on a boiler shall not exceed 10% of the highest pressure to which any valve is set.
(g)
When two or more boilers, operating at different pressures and safety valve settings, are interconnected, the lower pressure boilers or interconnected piping shall be equipped with safety valves of sufficient capacity to prevent overpressure, considering the maximum generating capacity of all boilers.
(h)
In those cases where the boiler is supplied with feed water directly from water mains without the use of feeding apparatus (not to include return traps), no safety valve shall be set at a pressure greater than 94% or the lowest pressure obtained in the supply main feeding the boiler.
(I)
If the safety valve or safety relief valve capacity cannot be computed or if it is desirable to prove the computations, it may be checked in any one of the three following ways, and if found insufficient, additional capacity shall be provided:
(1)
By making an accumulation test, which consists of shutting off all other steam discharge outlets from the boiler and forcing the fires to the maximum. The safety valve capacity shall be sufficient to prevent a rise of pressure in excess or 6% of the maximum allowable working pressure. This method should not be used on a boiler with a superheater or reheater;
35
(2)
By measuring the maximum amount of fuel that can be burned and computing the corresponding evaporative capacity(steam generating capacity) upon the basis of the heating value of this fuel. These computations shall be made as outlined in the Appendix of the ASME Code, Section I;
(3)
By measuring the maximum amount of feedwater that can be evaporated. When either of the methods outlined in Section 380:25-5-10(I)-(2) & (3) is employed, the sum of the safety valve capacity shall be equal to or greater than the maximum evaporative capacity (maximum steam generating capacity) of the boiler.
380:25-5-11. Boiler feeding

Each boiler shall have a feed supply which will permit it to be fed at any time while under pressure.
(b)
A boiler having more than 500 square feet of water heating surface shall have at least two suitable means of feeding, at least one of which shall be a feed pump. A source of feed at a pressure 6% greater than the set pressure of the safety valve with the highest setting may be considered one of the means. Boilers fired by gaseous, liquid, or solid fuel in suspension may be equipped with a single means of feeding water provided means are furnished for the shutoff of heat input prior to the water level reaching the lowest safe level.
(c)
The feedwater shall be introduced into the boiler in such manner that it will not be discharged close to the riveted joints of shell or furnace sheets, or directly against surfaces exposed to products of combustion, or to direct radiation from the fire.
(d)
The feed piping to the boiler shall be provided with a check valve near the boiler and a valve or cock between the check valve and the boiler. When two or more boilers are fed from a common source, there shall also be a valve on the branch to each boiler between the check valve and the source of supply. Whenever a globe valve is used on feed piping, the inlet shall be under the disk of the valve.
(e)
In all cases where returns are fed back to the boiler by gravity, there shall be a check valve and stop valve in each return line, the stop valve to be placed between the boiler and the check valve, and both shall be located as close to the boiler as is practicable. It is recommended that no stop valves be placed in the supply and return pipe connections of a single boiler installation.
380:25-5-12. Water level indicators
(a)
No outlet connections (except for damper regulator, feedwater regulator, low water fuel cutout, drains, steam gauges, or such apparatus that does not permit the escape of an appreciable amount of steam or water therefrom) shall be placed on the piping that connects the water column to the boiler. The water column shall be provided with a valved drain of at least 3/4 inch pipe size, the discharge to be piped to a safe location.

The steam gauge shall be connected to a siphon or equivalent device of sufficient capacity to keep the gauge tube filled with water and so arranged that the gauge cannot be shut off from the boiler except by a cock placed near the gauge and provided with a tee or lever handle arranged to be parallel to the pipe in which it is located when the cock is open.
(b)
When a steam gauge connection longer than 8 feet becomes necessary, a shut-off valve may be used near the boiler provided the valve is of the outside-screw-and-yoke type and is locked open. The line shall be of ample size with provision for free blowing.
(c)
Each boiler shall be provided with a 1/4 inch or larger nipple and globe valve connected to the steam space for the exclusive purpose of attaching a test gauge when the boiler is in service so that the accuracy of the boiler steam gauge may be ascertained.
380:25-5-14. Stop valves
(a)
Each steam outlet from a boiler (except safety valve and water column connections) shall be fitted with at least one stop valve located as close as practicable to the boiler.
(b)
When a stop valve is so located that water can accumulate, ample drains shall be provided. The drainage shall be piped to a safe location and shall not be discharged on the top of the boiler or its setting.
(c)
When boilers provided with manholes are connected to a common steam main, the steam connection from each boiler shall be fitted with two stop valves having ample free blow drain between them. The discharge of the drain shall be visible to the operator while manipulating the valve closest to the boiler and shall be piped clear of the boiler setting. The stop valves shall consist preferably of one automatic nonreturn valve (set next to the boiler) and a second valve of the outside-screw-and-yoke type.
380:25-5-15. Blowoff connection
(a)
The construction of the setting around each blowoff pipe shall permit free expansion and contraction. Careful attention shall be given to the problem of sealing these setting openings without restricting the movement of the blowoff piping.
(b)
All blowoff piping, when exposed to furnace heat, shall be protected by fire brick or other heat resisting material. It shall be so constructed that the piping may be inspected readily.
(c)
Each boiler shall have a blowoff pipe, fitted with a valve or cock, in direct connection with the lowest water space. Cocks shall be of the gland or guard type and suitable for the pressure allowed. The use of globe valves shall not be permitted. When the maximum allowable working
37
pressure exceeds 100 psig, each blowoff pipe shall be provided with two valves or a valve and cock.
(d)
When the maximum allowable working pressure exceeds 100 psig, blowoff piping shall be at least extra heavy steel from the boiler to the valve or valves, and shall be run full size without use of reducers or bushings. The piping shall not be galvanized.
(e)
All fittings between the boiler and blowoff valve shall be of steel. In case of renewal of blowoff pipe or fittings, they shall be installed in accordance with the rules and regulations for new installations. See National Board recommended rules for Boiler Blowoff Equipment.
380:25-5-16. Repairs and renewals of boiler fittings and appliances

(6)
Safety relief valve capacity for each boiler shall be such that, with the fuel burning equipment installed and operated at maximum capacity, the pressure cannot rise more than 10 percent above the maximum allowable working pressure. When more than one safety
41
relief valve is used, the over pressure shall be limited to 10 percent above the set pressure of the highest set valve allowed by Section 380:25-5-25(a)(1).
(7)
If there is any doubt as to the capacity of the safety relief valve, an accumulation test may be run (See ASME Code, Section VI, Recommended Rules for Care and Operation of Heating Boilers).
(8)
No valve of any description shall be placed between the safety relief valve and the boiler, or on the discharge pipe between the safety relief valve and the atmosphere. THE DISCHARGE PIPE SHALL NOT BE LESS THAN THE DIAMETER OF THE SAFETY VALVE OUTLET AND FITTED WITH AN OPEN DRAIN TO PREVENT WATER LODGING IN THE UPPER PART OF THE SAFETY VALVE OR IN THE DISCHARGE PIPE. When an elbow is placed on the safety relief valve discharge pipe, it shall be located close to the safety relief valve outlet, or the discharge pipe shall be securely anchored and supported. All safety relief valve discharges shall be so located or piped as not to endanger persons working in the area.

(ii)
When a Y-base is used, the inlet area shall be not less than the combined outlet areas. When the size of the water heater requires a safety relief valve larger that 4 ½ in. diameter, two or more valves having the required combined capacity shall be used. When two or more valves are used on a water heater, they may be single, directly attached, or mounted on a Y-base.
42
(C)
Threaded connections. A threaded connection may be used for attaching a valve.
(D)
Prohibited mountings. Safety relief valves shall not be connected to an internal pipe in the water heater or a cold water feed line connected to the water heater.
(E)
Use of shutoff valves prohibited. No shutoff of any description shall be placed between the safety relief valve and the water heater, or on discharge pipes between such valves and the atmosphere.
(F)
Safety relief valve discharge piping.
(I)
A discharge pipe shall be installed on the outlet of a safety relief valve, and when a discharge pipe is used, its internal cross-sectional area shall be not less than the full area of the valve outlet or of the total of the valve outlets discharging thereunto, and shall be as short and straight as possible and so arranged as to avoid undue stress on the valve or valves. When an elbow is placed on a safety relief discharge pipe, it shall be located close to the valve outlet.
(ii)
The discharge from safety relief valves shall be so arranged that there will be no danger of scalding attendants. When the safety relief valve discharge is piped away from the water heater to the point of discharge, there shall be provisions for properly draining the piping and valve body. The size and arrangement of discharge piping shall be such that any pressure that may exist or develop will not reduce the relieving capacity of the relieving devices below that required to protect the water heater.
(2) Water supply.
(A)
Connections. Water supply shall be introduced into a water heater through an independent water supply connection. Feedwater shall not be introduced through openings or connections provided for cleaning, safety relief valves, drain, pressure gauge, or temperature gauge.
(B)
Pressure. If the water supply pressure to a water heater exceeds 75% of the set pressure of the safety relief valve, a pressure reducing valve is required.
(C)
Stop valves. A stop valve shall be placed in the water supply pipe connections of an ASME code stamped water heater installation and should be placed in the discharge connection.
(D)
Bottom drain valve.
43
(I)
Each water heater shall have a bottom drain pipe connection fitted with a valve or cock connected with the lowest water space practicable. The minimum size bottom drain valve shall be 3/4 in.
(ii)
Any discharge piping connected to the bottom drain connection shall be full size to the point of discharge.
(E)
Thermometer. Each installed water heater shall have a thermometer so located and connected that it shall be easily readable. The thermometer shall be so located that it shall at all times indicate the temperature in degrees Fahrenheit of the water in the hot water heater at or near the outlet.
